Why does an altruistically inclined player behave altruistically in some contexts and egoistically or spitefully in others? This article provides an economic explanation to this question. The basic argument is centered on the idea that social norms shape our preferences through a process of...

This paper studies the welfare implications of equilibrium behavior in a market characterized by competition between two interconnected telecommunication firms, subject to constraints: the customers belong to a social network. It also shows that social networks matter because equilibrium prices...

Global games emerged as an approach to equilibrium selection. For a general setting with supermodular payoffs unique selection of equilibrium has been obtained through iterative elimination of strictly dominated strategies. For the case of global games with strategic substitutes, uniqueness of...

We model dynamic mechanisms for a global commons. Countries benefit from both consumption and aggregate conservation of an open access resource. A country's relative value of consumption-to-conservation is privately observed and evolves stochastically. An optimal quota maximizes world welfare...

We propose a model of strong reciprocity and trust that combines elements of personality psychology and behavioral economics. In the model, positive reciprocity and negative reciprocity are components of individual utility functions, while trust is an individual bias that distorts the beliefs...

Background: In this paper we present an economic evaluation of policies aimed at increasing deceased organ donation in Chile, a developing country that has low donation rates; 5,4 donors per million people (pmp) in 2010. Methods: Expert opinion of leading participants in donation and...

In this paper we estimate cost savings for the health-care system and quality of life improvement for patients from an increase in the number of kidney transplants in Chile. To do so, we compare the present value of dialysis and transplantation costs and quality of life in a 20-year horizon. We...

In this paper we study the role of resale opportunities in secondary markets over the bidding process in first and second price auctions. This trade opportunity arises owing to the presence of two factors. On the one hand, after receiving the object, the winner obtains new information about the...

Network formation is frequently modeled using link-formation games and typically present a multiplicity of Nash equilibria. Cooperative refinements - such as strong or coalitional proof Nash equilibria - have been the standard tool used for equilibrium selection in these games. Non-cooperative...
